Again, not having to worry about `mark-up` _<rules>_ in SYNOPSIS section
is very nice.

You may already have explained the rules elsewhere, but please
help me refresh my memory with some explanation.

Here, we just say `everything in literal, including placeholders`,
which is very pleasant for us writers.

Why aren't these `-1 --base` and instead mark up individual tokens?

This has to do the _italics_ for placeholders, unlike the full
command line examples we saw earlier?

Where does this difference come from?

Thanks.
